# There was a bug that affected the `Translate()` when no targets were provided
# explicitelly via argument list. If, for exapmle, `pkg1/SConscript` and 
# `pkg2/SConscript` scripts in some project `p1` had:
#
#       Translate(LINGUAS_FILE = 1)
#
# then target languages defined in `pkg1/LINGUAS` would affect the list of
# target languages emitted by `pkg2/SConscript` and vice versa.
#
# The pull request #64 on bitbucket fixes this. Here is the test case to
# replicate the bug.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
